Seeing the check engine light come on instills a sense of dread in many drivers. After all, although it indicates a problem, it doesn’t tell you exactly what it is. Fortunately, say the auto repair specialists at Brown County Automotive in Mount Orab, Ohio, it’s usually just one of a few issues. Here, they list three of the most common ones. 

Auto Repair Experts List 3 Reasons Your Check Engine Light Is On

1. The Gas Cap Is Loose

This is especially common when you have your tank filled by someone else. They might have put the gas cap back on crooked or completely forgotten to replace it. Usually, you’ll get a few miles down the road before the light comes on. So, if you see it and you filled up your tank recently, check the cap first. 

2. Your Catalytic Converter Needs to Be Replaced

The catalytic converter creates a chemical reaction that converts harmful gases emitted from the car into less toxic or even neutral substances. If it’s damaged, it’s likely due to a lack of maintenance, and it will need to be replaced. Common signs your catalytic converter isn’t working properly aside from your check engine light being on are a sudden drop in your vehicle’s fuel efficiency, your car not accelerating, and your vehicle refusing to turn on. Driving around without a functioning catalytic converter is illegal in most states, so it’s essential to get it repaired.

3. A Spark Plug Needs to Be Replaced

Without spark plugs, it can be pretty difficult to start your car, as they’re used to ignite the combustion. Typically, issues occur when they’re worn out and need to be replaced. If you have trouble starting your car or your engine often misfires, this can be a sign your spark plugs are worn out. It’s best to consult a professional at an auto repair shop to be sure.
